The ,twfzeememmg' Jewel; f

Assuming that anumberhaskbeen set upon` the key-board iandthat the lifting bars 2O` in the travelingcarriage havebeen.posil l tioned, the handle is now pulledtojintroducev I the number into. the totalizer, which opera-ffm?. tion` effects thefollowing As the sidefra'mes 29 and 30 rise bythe action andthe fiuctuationy of the cam 35, the traveling` carriageA mitsthe -v-frame-platcsev29, and 30 to remain.` l' f stationary: k'The further' movementgottheg l handle willjelevatesai'd frame 'plates and."` vthe finalmovement 'of the handlelwill hold i l them elevat dwhilefthe handle continues its 1.100 l i will likewise rise.` y It is `obviousA `,that the traveling carriage must be heldin ffivxedy positionv on itstrack rails iu this movemenh so" as toA prevent 'accidental displacement thereof which `mightdestroy registration,bel-y tween the;` positioned l.lifting bars ,andy the (s with vvhich` crank Alever strikes. a, confining" bailllfif4`2 i mounted` zon the "guiding L part l which l pl I i ing the lifting bars forward and the travelsecuredto the upper end vofthe posts 1d and holds the upper end of the bell-crank' lever out of engagement with the notches and plate 24 whereby the carriage can travel in either direction. When, however, the

handle starts to move forward and lifts the frame-plates 29 and 30, the locking pawl 40 is likewise lifted so that its upper end will engage with a registering notch in the n ing carria e having been locked in position upon the initial lifting movement, the continued `upward movement of the traveling carriage will cause the lifting pins or Lbars 20 therein to come 'into contact with overhanging projections or shoulders 43a on the rack bars 43. These shoulders are pref- 'erably made slightly wider than the thickness of the rack bars so as to afford an ample bearing-face for coperation with the lifting pins or bars. (See Fig; 6'.) These racks 43 are guided -in their vertcial movement byv Vthe plates 27 and bycross-bars arranged lbetween the side frames of the plates which house the printing mechanism to be hereinafter referred to. The upper ends of these racks 43 carry printing type 44 which are brought into printing line opposite the platen and struck by'hammers of a printing mechanism which will be hereinafter described. It is obvious that the 9 'lifting lpin will first come in contact with its shoulder 43*I and that the 1 7 lifting pin will be the last to come in contact with its shoulder 43a. When, however,these lifting pins have all been raised against. theirfrespective shoulders and the racks 43 are lifted, whether on anexcursion of one toothor nine teeth, the first upward movement of said racks will cause the locking bars 45, pivoted to the rear edges of the racks and having a jog or bend 45a constituting a cam -face or coperating with the bail 42, hereinafter referred to, to be swung so that their upper ends will move into position under the liftingr pins in engagementk with the active racks, respectively. By lthis means the lifting pins are positively locked to the racks' andcan partake of no independent vertical y movement.

As the traveling carriage is positively raised and lowered it will be observed that in thus locking the racks thereto the racks likewisefmust be positively raised and lowered iny their Vdifferential excursions and hence no over or under'throwl ofthe racks is possible. -As the'racks descend afterhaving completed their excursion, whether; of,

one toothA or nine teeth, the jog or bend 45a will engage the beveled edge of' plate 27 and move lthe'upper end of the locking bar 45 from` under the lifting pin with which it had coperated. When ther racks are differentially raised bv the'lifting pins, the totalizer is throwninto mesh Vtherewith-so thatthe denominational wheels thereof will be Vrotated `upon the vdownward movement of the racks in the introduction ofl items into the totalizer. Referring nowto Fig. 2, 46 indicates the totalizer wheelsfwhich are strung on a shaft 38 `which shaft is mounted in a rockingframef 48 ywhose lowerl end is pivoted upon a shaftv 49. The meansk for effecting the engagement and disengagement between the totalizer wheels and the racks is best seen in Fig. 12, wherein it will 'be'observed that one of the cam plates 35', before referred to, is provided with apin 50which, when the cam rplate 35 is rocked forwardly'and just prior to the Vcompletion of thle` forward movement thereof, will come in contact with a bell-crank'lever V51 pivotally mounted on a shaft 52, extending beyond one of the frame plates which houses the carrying mechanism.

The otherend ofthis bell-crank lever 51 is providedxwith a plate 53 which is adjustable ltoward and fromthe pivot shaft 52 whereby the throw of the totalizerca'rrying-frame 48A may be adjusted to take up any wear.y This plate' 53 has a supplemental plate 54 mounted'thereon `and containing a V-shaped notch'in its'rear edge, which notch coperates with'a pin 55 on the upper end 1 of one ofthe frame plates 48. The plate 53 is also` provided with a V-shaped notch shown in-dot'ted lines, but it is deeper than the notch in the plate 54. When the plates 53' and 54 arel adjusted relative to each other,

the notch 'in the plat'ev53 will control the en-- ement between the totalizer wheels and racks, making such engagement adjustable` so as to avoid as much lost motion as possible vvand at the same time prevent undue friction. The shallow notch in plate 54 adjusts the totalizer wheels with respect to the carrying segments and likewise avoids lostv motion and prevents undue friction.

The inclined surfaces of the V-shaped notches in the'plates 53 and 54 may thus be made g to intersect each other for the purpose mentioned,da's the pin 55, in the two positionsV ofthe vtotalizer wheels, will engage the outer edges `only of the notch in the plate 53`and the bottom of the notch in plate 54 in its relation to the racks and carrying segments, respectively. This adjustment also enables the partsto` be adjusted tocompensate for irregularities-in manufacture. The plate 53 is provided with ahook portion 53l at' itsI ubell-"crvalilr` leyerifafter operatingit; .i I i n Thenpperend @framers @umgesehen '58 ,-up'o'hwhich'are Imounted a series oftrip- 'I `held outwardlywintothe pathofm cam-"face Y fthe `retaining outer rear edge whose function is to 'engage i end` hold the' i totalizerv wheels intovengagement withthevracks` duringthe rearward mvementofnthe handle.

From kthe abovejt .will be seenthat as thel i' handle "approaches, the" forward `extremity ofits movement, thepin `50 willlengagethe belly-crank 51' and move the plates 53 and-54 downwardly until the hook 53n engages" the pin As the handle starts rearwardly,

The totalkey bar 73 is provided with an opening 73* into which this latch normally rests, biitqo when the total key is depressed the lower edge` .of thel openin engages. the` inclined face of the latch to orce the same laterally, `and when the latch is released it will be.

swung under the totalkey, as shown in Fig. '7 5 11, To release the total key when the handle reaches the'forward limitof its movement, .an arm 81 secured on the shaft 36 through the medium ofva cam face on the lower edge thereof, engages apin 77,b on theV plate 77 yandfinoves lthe latch 77"* from under lthe ,total-key.

4state that theshaft 38 on which thetotalizer wheels are mounted, is provided with aslot for longitudinal groove (see Fig. 18) in .whiohis mounted a comb-plate 82 whoseilm teeth `project through slots in washers interposed between the totalizer wheels. lThe comb"teethnormally lie between the totalizer wheels in'such a position thatthey `will y ,notengage or interfere withtheirgindepend- .115 `Vent rotation, but when the teeth ,occupy a `position wherein they willengage the tripping projection of the doublefaced ,tooth of each. totalizer wheel, and, as the shaft carrying the comb-plate is lrotated, said comb teeth willi pick` up` the `totalizer wheels,

.or such of them as have been operated and .moved to a `position other .than the zero position, and positively rotate them to their zero position.

. `125 .This comb-plate has one end connected to .a collarv84 mounted onthe` shaft 38, which collar has a reduced annulus for coperating with a forked arm 85 pinned to the'lozi'- gitudinally movable shaft 86. (See Fig.
